Identify the wreck and prepare a return point
Look for the crashed, smoking UFO in the snow. The unlock guide identifies it behind the tallest northern peak, where the Yeti can interrupt your approach. No shop purchase or prior character unlock is listed for the UFO itself.
A respawn anchor near the approach helps with retries. The recorded PC controls use hold 1 to place an anchor and hold 2 to return; check the input table if your bindings differ.

Travel from the lodge to the north
Take the left lift uphill
Cyanrabitt’s discovery starts at the lodge entrance: take the lift on the left all the way to the high mountain.
Find the paired rocks at the top
Look to the left of the lift’s upper end for two rocks forming a V-shaped gap. Place your return anchor on the safe side before crossing.
Cross beyond the rocks
Pass through the gap and continue over the hill ahead. As the blizzard begins, the Yeti area starts; the discovery report places the wreck to the left after cresting that hill.
Interact quickly at the wreck
Approach the smoking UFO and use the interaction prompt before a Yeti kick carries you away. If interrupted, return to your anchor and retry the approach.

Confirm the sled unlock
Confirm the UFO reward notification, then check your sled selection for the UFO. Walking near the wreck or being kicked by the Yeti alone is not the recorded acquisition action.
If you are comparing it with other sleds, use the sled comparison. The UFO’s appearance and player handling preferences do not establish a measured speed advantage.
